2019-05-01mt76: fix tx power issuesFelix Fietkau5-13/+9
- tx power is stored in the channels after ieee80211_register_hw, so chan->orig_mpwr needs to be updated as well - for non-TSSI devices, mt76x2e needs to use a different target power value from the EEPROM - fix a rounding error in a few places (need to round up, not down) Signed-off-by: Felix Fietkau <[email protected]>

2019-05-01mt76x02: make beacon slots bigger for USBStanislaw Gruszka4-37/+22
Since we sent PS buffered frames via beacon memory we need to make beacon slots bigger. That imply we will also need to decrease number of slots as beacon SRAM memory is limited to 8kB. Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>

Program beacons data and PS buffered frames on TBTT work for USB. We do not have MT_TXQ_PSD queue available via USB endpoints. The way we can send PS broadcast frames in timely manner before PS stations go sleep again is program them in beacon data area. Hardware do not modify those frames since TXWI is properly configured. mt76x02_mac_set_beacon() already handle this and free no longer used frames.

2019-04-30ipv6: fix races in ip6_dst_destroy()Eric Dumazet2-10/+3
We had many syzbot reports that seem to be caused by use-after-free of struct fib6_info. ip6_dst_destroy(), fib6_drop_pcpu_from() and rt6_remove_exception() are writers vs rt->from, and use non consistent synchronization among themselves. Switching to xchg() will solve the issues with no possible lockdep issues.

2019-04-30Merge branch 'Convert-mv88e6060-to-mdio-device'David S. Miller9-986/+53
Andrew Lunn says: ==================== Convert mv88e6060 to mdio device This patchset builds upon the previous patches to mv88e6060. It adds support for probing the switch as an MDIO device and then removes the legacy probe method. Since this is the last device supporting legacy probe, this allows legacy probe to be removed, originally planned to be removed in 4.17, but took a bit longer. This change to the mv88e6060 is more risky than the previous patchset. Some attempts to test it have been made, by hacking the driver to match on an mv88e6352 so that it probes. These changes are all about probe, so it is a reasonable test. But testing on a real mv88e6060 would be great. ==================== Signed-off-by: David S. Miller <[email protected]>
